Creates explicit artifacts for each classifier in config.module, and then attempts to resolve them directly.

Creates explicit artifacts for each classifier in config.module, and then attempts to resolve them directly. This
is for Maven compatibility, where these artifacts are not "published" in the POM, so they don't end up in the Ivy
that sbt generates for them either.
Artifacts can be obtained from calling toSeq on UpdateReport.
In addition, retrieves specific Ivy artifacts if they have one of the requested config.configuration.types.

config

important to set config.configuration.types to only allow artifact types that can correspond to
"classified" artifacts (sources and javadocs).
